In a first, an international team of scientists has discovered an exoplanet with no clouds.
The team, led by Nikolay Nikolov, an astronomer at the University of Exeter in the United Kingdom, detected this hot gas giant, known as WASP-96b, using the European Southern Observatory's Very Large Telescope in Chile. The team determined the atmospheric makeup of the exoplanet by studying it as it passed in front of its host star and measuring how the planet and its atmosphere affected light from the star.
A planet's atmospheric makeup influences the light that scientists can measure as it passes by its host star. This creates a spectrum, which is like a unique fingerprint. Typically, clouds obscure the light released by a planet and affect the spectrum that researchers can study from Earth, according to a statement released yesterday (May 7) by the University of Exeter.
